English to Spanish Law/Patents Law: Contract(s)

Necesitaría ayuda para traducir esta expresión que aparece en varias ocasiones en un contrato. Varios ejemplos:

"To secure Seller’s rights in the event of the goods being processed or mixed with other third-party products, Customer assigns to Seller **already now** co-ownership of the new goods"


"Customer assigns to Seller **already now** as security any claims arising from the sale of goods in which Seller retains any property rights, to the extent corresponding to Seller’s co-ownership of the goods sold"

Muchísimas gracias a todos!
